“…Ersahin et al also outlined that a DM layer plays an important role in organic matter removal [18]. Benjamin's research group developed a hybrid adsorbent/membrane process comprising a pre-treatment step, in which water was passed through a pre-deposited layer of HAOPs (heated aluminum oxide particles), followed by a conventional membrane filtration [1,[19][20][21][22][23][24][25][26][27][28][29][30]. That process was applied for the first time by Kim et al (2007) [23].…”

“…HAOPs have been synthesized in order to remove major foulants, such as natural organic matter (NOM), from surface water and also to mitigate the fouling of the downstream membrane. As such, they are adsorbents that combine adsorption and granular media filtration [19][20][21][22][23][24][25][26][27][28][29][30].…”

“…Since the deposition of HAOPs involves the integration of a granular media filtration and a packed bed adsorption, the feed water is required to pass through a layer of predeposited adsorbent on a filtering media. Such DM adsorber has been reported to be very efficient in the reduction in both NOM and the fouling [19,[21][22][23][24][25][26][27][28][29][30]. Although DMs containing HAOPs have been investigated for the removal of phosphorus from the effluent produced by a membrane bioreactor (MBR) [20,24], they have not yet been investigated for removal of phosphorus from the surface water.…”

On the one hand, Kim et al (2008) reported that iron oxides have superior adsorption affinity to phosphorus, when compared to HAOPs [21].…”

The paper reports the removal of phosphorus and natural organic matter (NOM) from surface water by dynamic membrane (DM) adsorber. DM filter builds up as a layer of particles deposited via permeation through the membrane’s surface. This study reports the application of Heated Aluminium Oxide Particles (HAOPs) as a dynamic membrane adsorber. Filtration experiments were conducted with surface water and batch tests were carried out with synthetic water. The efficiency of phosphorus removal along with the efficiency of organics (represented as UV-254) removal was evaluated. Additionally, the impact of HAOPs surface loading on the changes of transmembrane pressure (TMP), the kinetics, isotherm modeling of the adsorption and the effect of the pH, the effect of ionic strength, the effect of coexisting organic matter on phosphorus removal efficiency were studied. In the case of phosphorus removal in batch adsorption experiments, its sorption kinetic and isotherm data were analyzed using pseudo-first- and pseudo-second-order models and Langmuir and Freundlich models, respectively. The results indicated that Langmuir adsorption isotherm fits the experimental data best (0.9894). The kinetics of phosphorus adsorption on HAOPs was best described by the pseudo-second-order model and the best removal was achieved at the pH 6–7 (96.65% on average). An increase in ionic strength did not impact the efficiency of phosphorus removal significantly. The outcome of this study highlights HAOPs efficiency in NOM removal up to 92% in filtration experiments. In the case of phosphorous, removal efficiency varied. For the highest HAOPs dose, the degree of phosphorus removal ranged up to 93 ± 5%. The same removal efficiency was observed for the lowest dose while for 17 g/m2 of HAOPs the fluctuations were larger and varied from 64.7% to 92%. The results demonstrate that HAOPs could potentially be applied in the removal of phosphorus from surface water, especially when there is a high concentration of phosphorus in the water. However, this process requires further research and optimization of its parameters.

“…Therefore, several efforts have been made to increase water quality by removing the undesired elements such as nitrate and phosphorus. Among these efforts, marble dust [2], aluminum oxide particles [4], and bimetallic nanoparticles [5] were used as sorbents for phosphorus. Additionally, surfactant-modified zeolites [6], carbon nanotube [7], and chitosan nanofibers [8] were among the most used nanomaterials for nitrate removal.…”

This work aims to demonstrate the effect of polyethylene sorbitan monolaurate (PSM) on the properties and reactivity of nanoscale zero-valent iron (nZVI). PSM was used in this work to prepare an emulsified nZVI to overcome the particle aggregation phenomenon of nZVI and show the prepared particles with good properties. For that purpose, TEM, XRD and reactivity test of nitrate and phosphorus were performed to show the changes in the performance of nZVI after being emulsified with PSM. The results showed that the emulsified (PSM) greatly improved the removal efficiency of nitrate. Moreover, PSM enhanced the particle dispersion of nZVI and showed the particles with good properties . The results showed that the emulsified nZVI with PSM was also suitable for reduction of nitrate even at a wide range of pH. This study proposed that the emulsified nZVI could have a significant contribution in the aspects of water treatment only for the reducible contaminates.
